Hello gentleman...
It’s almost intimidating reading about the exotic systems and what you do with them. I have a rather challenging room, irregular in shape and all mirror behind me. I’ve moved the sofa 14" from the rear mirrored wall and propped a couple large pillows behind where my head position is. With and without the pillows, there’s a huge difference so I am a believer in room treatments. Plus what I remember from sound engineering school.
As far as IC’s, I budget about $80 - $100 per IC, most all Audioquest. Speakers are Paradigm Signature S2 FL/FR, Paradigm Studio 20 V5 SL&SR, 3 REL sub base, and the weakest point is my center, Paradigm CC-490. Amp is an Anthem A5, Integra DTR-50.3 which now serves as my pre, Oppo BDP 103, and just added a REGA Apollo R. This system is dual purpose HT and music. When I listen to music, it’s direct stereo with no eq, only one sub base REL R528. the marriage of the S2’s and the R-528 are awesome!
I guess the point to all this is.. Room acoustics are a huge link in the chain. IC’s are a subtle but noticeable link, speaker position, huge link, components, huge link. Every component, IC, room characteristic, makes huge and subtle differences. All this keeps us more than busy and fun to boot...
Oh, I'm also adding a TEAC X200R to my system. Plan to record some favorite stuff and bathe in nirvana. I understand analog tape rivals vinyl....
